-# WinAVR Sample makefile written by Eric B. Weddington, J�rg Wunsch, et al.

-# Released to the Public Domain

-# Please read the make user manual!

-#  Markus Pfaff

-#  Stefan Schuermans

-#

-# On command line:

-#

-# make all = Make software.

-#

-# make clean = Clean out built project files.

-#

-# make coff = Convert ELF to AVR COFF (for use with AVR Studio 3.x or VMLAB).

-#

-# make extcoff = Convert ELF to AVR Extended COFF (for use with AVR Studio

-#                4.07 or greater).

-#

-# make program_fuses = Set the fuse bits of the device, using avrdude.  Please

-#                      customize the avrdude settings below first!

-#

-# make program = Download the hex file to the device, using avrdude.  Please

-#                customize the avrdude settings below first!

-#

-# make filename.s = Just compile filename.c into the assembler code only

-# To rebuild project do "make clean" then "make all".

-

-# List Assembler source files here.

-# Make them always end in a capital .S.  Files ending in a lowercase .s

-# will not be considered source files but generated files (assembler

-# output from the compiler), and will be deleted upon "make clean"!
